Handy https://handy.computer/ is a free and open source voice transcription app. Works on macOS, Linux, and Windows, and you can pick which model. Everything runs locally. There is no API.

I use the app constantly, all day long.

I just fired this up at work, and it was so seamless and my few small tests worked well.

I have it bound to a mouse button. Something to try! Also I have "enter" bound to another mouse button. I hold down one to talk, then when it's done transcribing I press enter. I use an MMO Mouse, the $50 Corsair Scimitar.
